Can I do Delta online check-in for my friend or family member?

Usually you can, if you have the right details:

• Their confirmation number and last name, or their SkyMiles number
• The same website or Fly Delta app flow you’d use for yourself
• Their passport or ID details if the trip is international

If you’re on the same reservation, you can usually check everyone in together. If it is a separate booking, check each one separately. Make sure they save their own boarding pass too. This Delta online check-in guide covers the steps.
